Paris Hilton Darkens Up Her Namesake City

Paris Hilton decided to wear a brown wig while shopping in Paris on Thursday. Why? Well, it might have had something to do with the star reportedly going shopping in a spy store and she wanted to play the part. Or maybe Paris just wanted to try and be unrecognizable by her fans? Either way, when her sister Nicky Hilton arrived to join her shopping, the jig was up!

Paris seemed to get a kick out of wearing the brown wig as she walked around the store, but it didn't last for very long.
